Suggestions for high pressure/velocity pumping of diluted tempera paint.
I've received the request to build a theatrical prop that should be able to shoot a diluted tempera paint 30- 50' from the gun. Any suggestions for where to begin looking for a pump capable of that kind of pressure or velocity to shoot a relatively narrow stream great distances? I don't think water pumps would be able to handle the extra viscosity of the diluted paint. This would not be aimed at anyone, but over a dance crowd. Amazingly, people pay money for this experience. Anyone know what the guy with this green paint is using? Looks like a miniature fire hose.
Many thanks for any suggestions! Instructables members are a talented and diverse bunch!
Everyone's answers have been very helpful. Through your suggestions and additional research we have determined that portable fire fighting pumps are the simplest method for moving a diluted paint solution great distances. The suggestions for using pressurized bursts of paint have also been helpful. Thanks everyone!
